In a revealing episode of Problem Child in House (Episode 5), several Kdrama actors offered a rare peek into the real-life challenges behind their on-screen roles. Beneath the polished visuals and compelling stories, this candid conversation reminded viewers just how demanding and exhausting the industry can be. From grueling body transformations to pushing through deep-seated shyness, the episode gave raw insight into what it really takes to succeed in the world of Korean dramas. The truth is, Kdrama behind the scenes is far from glamorous—it’s filled with silent sacrifices.

The episode opened with a light-hearted moment when the cast commented on Junyoung’s noticeably red ears and face. While some thought it was due to discomfort, Junyoung quickly explained that he’s just naturally shy around strangers. Kim Jongkook sympathized, recalling how reserved he used to be during his Turbo days. Still, one member teased that Junyoung’s quietness might be mistaken for arrogance, which sparked laughter and playful back-and-forth.

It’s hard to imagine that this soft-spoken personality is the same actor known for chilling villain roles in D.P. and Mask Girl. But Junyoung explained that once the cameras roll, they give him a strange kind of freedom—a space where he can fully express himself without hesitation. That transformation, from shy introvert to powerful screen presence, is one of the many unseen feats that actors pull off in the world of Kdramas.

Kdrama Behind the Scenes: The Physical Toll of Transformation

The conversation shifted to the physical toll acting can take—especially when roles require major body changes. Junyoung shared how he bulked up for a gym director character, eating five meals a day and training rigorously. While he admitted much of the muscle is gone now, his body-fat percentage remains low enough that his abs are still slightly visible.

Meanwhile, Eunji’s transformation was even more intense. She gained 9kg for a role in just over a month, only to drop the weight again in just two weeks. Her method was grueling: three daily cardio sessions (morning and evening runs and midday cycling), strict calorie control, and a mostly plant-based diet. Her motivation wasn’t just professional—she also started working out due to spinal disc issues. Jongkook, her fitness inspiration, guided her through training at his gym. Eunji believes this extreme level of commitment helped her land her recent acting role.

Behind the Romance: Filming Love Scenes in Kdramas

Woojae also shared some behind-the-scenes tidbits from his romantic Kdrama role as a dentist opposite Apink’s Bomi. At first, he claimed there was no kiss scene, but a video playback proved otherwise. The cast roasted his awkward body positioning and hesitant gaze, with even Junyoung joking that Bomi clearly took the lead. When Jongkook’s past kiss scene with Ye Jiwon came up, he reacted with mock horror, saying it felt like “a workout session.”

These moments, though funny on the surface, highlight how even short romantic scenes come with pressure—especially knowing that the smallest awkward move will be judged by millions of viewers later. It’s all part of the high-stakes environment Kdrama actors navigate on set.

The Hidden Labor Behind Kdrama Perfection

What Problem Child in House revealed is what fans often forget: Kdrama actors don’t just memorize lines and look good in front of a camera. They take emotional risks, live under intense scrutiny, and go through serious physical transformations—all to make their characters come alive.

So when you watch a heartfelt confession or a kiss under the rain, remember the exhaustion, sweat, and anxiety hidden behind those few seconds of perfection. Kdrama behind the scenes is where the real work happens—and the sacrifices made there are what bring magic to the screen. For more Kdrama news, check out the link below.
